Hey,
I am planning to implement authenticated boot inspired from Pid Eins’ blog. I’ll be using pam mount for /home/user. I need to check integrity of all partitions.
I have been using luks+ext4 till now. I am hesistant hesitant to switch to zfs/btrfs, afraid I might fuck up.
A while back I accidently purged ‘/’ trying out timeshift which was my fault.
Should I use zfs/btrfs for /home/user? As for root, I’m considering luks+(zfs/btrfs) to be restorable to blank state.
My experience with btrfs is quite old now, but I remember being plauged with enospc errors requiring a lot of balancing to correct.
I have been running zfs for a decade or so now on a 6 disk array and the only issue I have had was the pool not being imported on boot sometimes but that seems fixed now. I recenty replaced 2 disks in that array and the whole replace / rebuild process went quite well. I felt confident there would be no uncorrectable read errors during the rebuild because the monthly scrub had recently run. Overall I’m quite impressed with zfs.
All that said I would never run a root filesystem with an out of tree kernel module. So I’m still using xfs on /
